How many 4 month olds strictly only take bottles still? And who does oatmeal & bottle? Or baby food & bottles?
What is your schedule for it? I'm doing oatmeal every morning (followed by a bottle) and then oatmeal at night (followed by a bottle) he doesn't seem to enjoy the oatmeal too too much, he will only take 5 spoonfuls if that! Sometimes he won't take any at all and he makes a nasty face at first.
(I mix his oatmeal with formula)
